The existence of the Unity engine can be traced back to 2017 The "in-process code injection" vulnerability in 2016 affected about 70% of the world's most popular mobile games. Hackers can gain access to Android, Windows, macOS and Linux systems through infected games and steal crypto wallet mnemonics or private keys. According to Cointelegraph, although the vulnerability has been confirmed, Google pointed out that the Play Store has "not detected" actual criminal cases.

Vulnerability scope and attack paths

Unity dominates the mobile game market, with more than 50% of new games built on it, making it possible for vulnerabilities to spread to a large number of players. Hackers can plant malicious code inside the application and then induce a fake login screen to trick users into entering their wallet password through overlay attacks, input capture or screenshots. However, the Google APP team said:

Based on our current detection, malicious apps that exploit this vulnerability have not been found in the Play Store.

Compared with Google Play, which is officially censored, the sideloading behavior of installing APK from third-party websites is higher risk. Not only does it lack pre-scanning, but it also cannot automatically obtain patches subsequently released by Unity and developers.

Unity has begun making patching tools available to partners and plans to update its guidance publicly next week. Before the patch is fully implemented, players can take four methods to protect their crypto assets:

• Update games and systems at any time
• Avoid downloading APKs from unknown sources
• Check and close unnecessary permissions, such as overlaying on other applications
• Separate devices that store large amounts of crypto assets from mobile phones used to play games
